The forward end of crank shaft 15 isprovided withl a bolt I l'e'yV 2() 'which maybe of the usualf, which is keyed orother'wise suitably/ffii i the crank shaftjl and heldhin'y lac'elb1 60 ratchet nut l21 used for con a taCh'ablecrank handle to 't e crankt i whenit is desired to manuallf f n The-crank shaftfl is also pi"ovif'iyledneal1 its forward end, and forwardly ofjthefirst 65- crank arm, with a cam wheel'23`fslio: Ii' iii/'defA tail `in Figure 8,'and whereinfth'e Lbo y p tion' of the wheel is in the. frIiiNfiDdis mounted Von the shaft 15 and provided 'iioii edgeport'ion with a dove tail seatidrifdl'ores--f 70 sion`V extending entirely 4across the the 'cam wheel 23 and adapted toj'i'e'cfei therein the correspondingly' dove ta l shape base portion 24 of a cam 25 vvliicrliA s driven laterally into place. This cam'fi2'5'lf'5f maybe made of material which is relativelyff hard as' compared with the material vof the f cam wheel 23. The cam 25 may be removed? from the carn'wheelV when the cam is worn so that `the cams are readily interchanged. Y i

The rear end portion of the crank shaftj15` is providedwith a second cam wheel 23 vhav-l ing a cam 25 thereon, and'these cams and" cam Vwheels are adapted to control therise andlfall of push rods 26 which control'the 85n operation fof intake valves as hereinafter pointed out. A flywheel 27 is mounted upon the rear end of lthe!crank;shaft 15 and theV crank shaft issuitably connected to afdrive Y shaft or the like depending upon the. par- 90A ticularuse forrwhich the f'engine-iis con'-l structed. j l

The crank case 19 carries a cylinder blockVA f which `in the present instance `is'lprovidedf i with two cylinders 28 opening up"hardly"i 95 through the block and closedbyrar'ylifider; head' 29 bolted or -othervvise'ff'siiitably'l'l 1"" cured .upon the cylinderblockf` The is providedl with a shallowcon avity i"i Vposition, and which is provided with the usual piston rings near its upper and lower Y ends, the latter for the purpose of sealing the exhaust port 33 when the pistonl is in a raised position. It will be noted that the exhaust port 33 is relatively large and extends for a considerable dist-ance in .one sideA of the cylinder 28, and that the wall through which the exhaust port 33 is formed is -reinforced by the provision o f webs or bars 34 which divide the exhaust port up into a plurality of separate passages.

The cylinder block is provided with the usual water jacket 35 and is also provided with guide tubes36 at opposite endsof the block for enclosing the push rods 26Vand also for returning oil from ythe head 29back into the crank case-19. The. lower end of eachpush rod 26 projects into the upper portion of the crank case 19 and is provided with a suitably shaped end adapted to seat in a valve lifterV cup 37 provided with a. depend-- through the head 29 ing shank slidably engaging througha valve lifter guide 38, andwhich at its lower end is adapted to bear against the cam wheel 23 and the cam 25. A relief spring 39 encircles the shank of the valve lifter cup 37 for normally urging the same upwardly and 'maintaining itin contact with the lower end of the push rod 26.

The crank shaft 15 is provided,adjacent to the' rear cam wheel 23, with a spiral gear Wheel 40 which meshes with a worm 41 on a shaft 42 which extends upwardly and through the crank shaft 19 for connection with a distributor 43 to drive the latter.

Connected to each crank portion of the shaft` 15 is a connecting rod 44. Each rod 44 exs tends upwardly into the adjacent cylinder 2,8 and is connected to the respective piston 30 inthe usual mannen The gear wheel 4,0 in the crank case is arranged to drive an oil pump 46 preferably located in the bottom of end ofthe shaft 42. 1 I- 7. A

rlhe push rods 26 are provided on-their up-y perends with sockets or depressions 47 into which engage balls 48 on the outer-end of the'rocker arms 49. VAThe rocker arms are the crank case 19 and connected to the lower u pon brackets 50carried by thevsaid head 2 9 of thev engine, and the free endsI of said arms 49 bear against the upper ends of valve stems 51 held4 normally in raised position by springs 52. The stems 51V extend inwardly and have valve discs 53 upontheir inner ends `adapted to seat over intake openings 54 extending through the head 29.,

The rocker arms 49 are housedwithin a :'1@ hood which is mountedon the head 29 of vend of a coupling 69which leads to pivot-ally mounted intermediate ytheir endsk wardend of a manifold chamber-` `This the engine for enclosing the rocker arms and confining oil fed thereto from leaving the arms 49 and adjacent parts Vso that the oil accumulating in the head 29- may pass off through the tubes 36 and back Vinto the crank case 19.

The rocker arms 49, and other adjacent partsof the valves, are enclosed within a hoodl n 55, Figurel, which has a flanged opening 56 at its rear end'to which an air cleaner may be att-ached, and at its `other end has a anged opening 57 for connection with a carburetor 58,--offany suitable type, and which in turn is connected to the` rear side of a blowerl casing 59. The blower is. of suitable size and preferably cylindrical in generall configuration. The blower is mount-ed'upon a bracket 60 which extends forwardly vfrom the cylinder block of the engine for yholding the blower in proper position so` that the shaft 61 of the blower provides at its outer end a support for the fan 62 adapted to coolthe engine. Between the fan 62yand the casing 59, the shaftr 61 is provided with a .pulley 63 over which: passes a drive belt 64 which is driven from thepulley 2O on the crank shaft 15. a

k.Aisfbestshovv'n in Figures 3, 4 and 5 the blower casing 59 is positioned eccentrically the form of a cylindrical block which slidably carries a plurality of blades 66. The blades 66 are relatively flat and are of substantially the widthbf the interior. of the casing 59 and are of a length adapted to entirely recede into slots 67 which are formed at spaced intervals vin the periphery of the blockV 65. These slot-s 671 extend entirely through the opposite sides of the blockV and are arranged substantially ata tangent with respect to the shaft 61. rThe blades 66 freely slide in the slots 67 so that by centrifugal force these blades are urged outwardlyragainst the inner wall of the casing 59 so as to seal the blades 66 thereagainst and create the desired pumping action.

Itwill be.V noted from Figure 3 that the carburetor 58 is connected to` one side of the casing 59 while the opposite side of the casing has a connection 68 adapted to receive one chamber 70 is bored in the leftupper por-l tion of the cylinder block and extends throughout the length ofthe head. Intermediate the end ofthe chamber 70 is a divided manifold passage 71 `which leads through the head 29 and communicates with the intake passages 54 for feeding fuel under pressure to the cylinders 28. f

the for-Y llO The intake chamber 70 is provided withV a Y ringed piston 73, the latter adapted to receive the pressure of the fuel from the blower carried on the inner end of a threaded rod v 76 which isadjustably mounted through av disc.77 screwed'into the outer end of the cylinder 7 2. s

A lock nut 78 is carried by the rod 7 6 for engagement against-the disc 77 tolock the rod 7 6 from movement when adjusted.- The cylinder 7 0 is provided at a suitable rear point,

and in one side, with an exhaust port 79 of` suitable size for venting the fuel chamber l when the pressure is raised sufficiently vto force the piston 7 3 backwardlyto an extent such that the port 79 will, be open to the chamber 70.

By adjustment of the spring 74 the pressure in the fuel chamber may be maintained substantially constant and the piston 7 3 will effectively relieve the sudden abnormally increased pressure upon back-fire in the engine.

A suitable butterfly or throttle valve 80 may be mounted in the forward end of the fuel chamber 7 O for controlling the passage of fuel to the-manifold 7l. The outer edge portion of each blade 66 may be provided with a suitable packing slip, or brass filler 82 therein adapted to bear against the inner wall of the casing 59 of the blower, as shown in Figure 5, for more edectively sealing the blade in the casing. j

The Vforward part of the crank case 19 is provided with a laterally disposed bracket 83 supporting a generator shaft 84 equipped with a pulley 85 which bea-rs against the inner side of the belt 64 so that the generator may be driven directly from the main pulley 2O on the crank shaft.

As shown in Figure 1, the crank case 19 carries at one side a water pump 86, the shaft of which is connected to the rear end of the generator shaft 84 which acts as its means of propulsion. The pump is provided with a feed pipe 88 which is carried upwardly to the jacket 35, and is also provided with a return pipe 89 which leads to the radiator, not

shown, the water flowing through the radiator and cooling system in the usual manner. The engine is equipped with spark plugs 90 which are grounded at one side in the engine in the usual manner and which at their other sides are connected to the high tension wires 91 which lead to the distributor 43.

In operation, the parts of the engine function in the general ordinary7 manner, and the crank shaft 15 in turning operates the gear 40 and also the cams 23 so as to control the opening and closing of the intake valves 53, the operation of the oil pump and distributor.

VThe pulley 2O on the crank shaft 15 drives the belt 64 which operates the generator and water pump through the pulley 63 and also drives the fan 62 and the blower which is mounted on or connected to the cam shaft 61.

The blower draws ina gasmixture through the carburetor 58the latter being supplied with warm airwhich passes through the hood 55 and an air cleaner or the like which may be mounted upon the connection .56.'y The blower delivers the mixture through the connection 69`to the intake passage 70 andl intake manifold 71, the pressure remaining constant incident to the operation of the spring pressed` piston or plunger 73 and, by adjustment "of the tension of the spring 7 4 the desired pressure'of theV fuel mixture may be maintained inthe manifold-71. A'

f As pressure is maintained at `all times in the intake manifold, the mixture isV maintained under pressure in the passage 54 so that when theintake valves 53 are opened the mixture under pressure is delivered'into the'- upper ends-of the cylinders 28. 'The intake valves 53 `are timed to admit the mixture under pressure at the instant the piston 30 closes the exhaust passage going upwards in the cylinder 28. Theadmixture is admitted to the upper end of the cylinder 28 during approximatelyI one-fourth of the upward stroke of the-piston 30. The intake valve 53 now closes, the piston continues its Iupward stroke and compresses' the admixture in the upper end of .the' cylinder 28 untill the piston reaches n substantially the top or dead center position when'` the spark is produced at'the plug 90, effecting an explosion and driving the piston 30 downwardly, lthe -pressure continuing against the piston until the latter uncovers the,r exhaust opening or openings 33 at which time the burnt gases are expelled. The exhaust'openings-33 are 'maintained open durin gtheV further downward movement of the pist-on 30V, and also until the piston rises toapproximately 1 one-fifth. of its stroke, at whichv time the .piston overlaps the exhaust ports or openings 33 and closes the same.

Itisa-pparent that uponback-fire in the engine, or undue pressure inthe blower, the spring supported plunger 73yields and is driven 4backwardly or outwardly a distance 'suiiicient to uncover the exhaust port '79 whereupon the `excess, pressure in the manifold and'in the feed` passage 70 is vented or relieved, and the plunger 73 is again'thrust inwardly, .orv forwardly to maintain the norf mal pressureinv the manifold-71. j

`The blower may beproportioned or regulated asto speed dependentupon the'neededfV volume', and thisfmay be varied. to suit thev best'operatin'g pressure according to the size and proportions of the partsof the engine. It is obvious that various changes and modifications may be made in the details of-construction and vdesign of the above specifically described embodiment of this invention 'without departing fromvthe Vspirit thereof, such:
